Full Title

Full titles differ between systems:

IPC:

Controlling fuel-injection pumps, e.g. of high-pressure injection type > not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered > Transmission of control impulse to pump control, e.g. with power drive or power assistance > non-mechanical, e.g. hydraulic > pneumatic

CPC:

Controlling fuel-injection pumps, e.g. of high pressure injection type (F02D3/00 takes precedence) > not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered > Transmission of control impulse to pump control, e.g. with power drive or power assistance > non-mechanical, e.g. hydraulic > pneumatic

No child classifications to compare. This is a leaf node in both IPC and CPC.
